Irmgard Neumann

Rheumatology (Oxford) 2020 May;59(Supplement_3):iii60-iii67

Vasculitis.at, Vienna, Austria.

ANCA-associated vasculitis (AAV) is a systemic, potentially organ and life threatening chronic autoimmune disease. With current management strategies, such as high-dose glucocorticoids in combination with cyclophosphamide or rituximab, outcomes have progressively improved with overall remission rates of 70-90%. However, relapse rates after discontinuation of therapy are consistently high, and treatment-related toxicity, mainly driven by glucocorticoids, still determines morbidity and quality of life.

[Anti B-cell-antibody treatment for maintenance of remission in granulomatosis with polyangiitis and microscopic polyangiitis].

Dtsch Med Wochenschr 2020 01 8;145(1):40-46. Epub 2020 Jan 8.

Klinik für Rheumatologie und Klinische Immunologie, Department Innere Medizin, Medizinische Fakultät, Universitätsklinikum Freiburg, Freiburg.

Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) are the most frequent primary necrotizing small vessel vasculitides. In these formerly fatal diseases remission can be induced by stage- and activity-adapted immunosuppressive regimens in the majority of patients. This does not lead to drug-free long-term remission or even cure. Read More

The color of skin: purple diseases of the skin, nails, and mucosa.

Clin Dermatol 2019 Sep - Oct;37(5):528-547. Epub 2019 Jul 17.

The Ronald O. Perelman Department of Dermatology, New York University School of Medicine, New York, New York, USA. Electronic address:

The color purple can be seen in several types of eruptions including inflammatory dermatoses like lichen planus, infectious dermatoses like ecthyma gangrenosum, neoplasms like Kaposi sarcoma, and vasculitis and vasculopathy. The current review focuses on the clinical appearance, pathophysiology, and treatment of several vasculitides and vasculopathies including capillaritis, cutaneous small-vessel vasculitis, immunoglobulin A (IgA) vasculitis, cryoglobulinemia, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, microscopic polyangiitis, polyarteritis nodosum, warfarin-induced skin necrosis, heparin-induced thrombocytopenia, purpura fulminans, antiphospholipid antibody syndrome, calciphylaxis, levamisole-induced vasculopathy, and thrombotic thrombocytopenic purpura. Dermatologists play a central role in treating patients with cutaneous vasculitis and vasculopathy and may have the opportunity to facilitate identification of systemic disease by diagnosing cutaneous vasculitis and vasculopathy.

Personalized Medicine in ANCA-Associated Vasculitis ANCA Specificity as the Guide?

Front Immunol 2019 6;10:2855. Epub 2019 Dec 6.

Rheumatology Unit, Division of Rheumatology, Allergy, and Immunology, Boston, MA, United States.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a small- to medium-vessel necrotizing vasculitis responsible for excess morbidity and mortality (1). The AAVs, which include granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA), are among the most difficult types of vasculitis to treat. Although clinicopathologic disease definitions have been used traditionally to categorize patients into one of these three diagnoses, more recently ANCA specificity for either proteinase 3 (PR3) or myeloperoxidase (MPO) has been advocated for the purpose of disease classification (2).

Rationale of concomitant cyclophosphamide for remission-induction in patients with antineutrophil cytoplasmic antibody-associated vasculitis: A propensity score-matched analysis of two nationwide prospective cohort studies.

Mod Rheumatol 2020 Jan 6:1-9. Epub 2020 Jan 6.

Okayama University, Okayama, Japan.

We evaluated the effectiveness of cyclophosphamide for patients with microscopic polyangiitis and granulomatosis with polyangiitis. Patients treated with cyclophosphamide and glucocorticoid (cyclophosphamide group) or glucocorticoid alone (non-cyclophosphamide group) for remission-induction were enrolled from two Japanese nationwide prospective inception cohort studies. The effectiveness and safety outcomes were compared before and after propensity score (PS)- matching. Read More
